Is UNII-N3Y22O955Z Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use UNII-N3Y22O955Z? Is UNII-N3Y22O955Z safe for nursing mother and child? Does UNII-N3Y22O955Z extracts into breast milk? Does UNII-N3Y22O955Z has any long term or short term side effects on infants? Can UNII-N3Y22O955Z influence milk supply or can UNII-N3Y22O955Z decrease milk supply in lactating mothers?

Information in this record refers to the use of UNII-N3Y22O955Z (Cr 51-ethylenediamine tetraacetic acid; Cr 51-EDTA) as a diagnostic agent for the estimation of glomerular filtration rate. The International Commission on Radiological Protection and other experts state that breastfeeding need not be interrupted after administration of Cr 51 edetate.[1][2] The United States Nuclear Regulatory Commission states that breastfeeding need not be interrupted after administration of Cr 51 edetate in doses of 60 MBq (1.6 mCi) or less to a nursing mother.[3] However, to follow the principle of keeping exposure "as low as reasonably achievable", some experts recommend nursing the infant just before administration of the radiopharmaceutical and interrupting breastfeeding for 3 to 6 hours after the dose, then expressing the milk completely once and discarding it. If the mother has expressed and saved milk prior to the examination, she can feed it to the infant during the period of nursing interruption.[4][5][6] Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital. When the radioactivity is at a safe level she may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[7]
